To all'whom'it, may concern: p

Be-it known that 1, Lewis J. B zaom, a citizen of the United States, residing at State of Massachusetts, have inventedcerain Improvements in the Manufacture of hoes, of which the following descri tion, in connection with the accompanying rawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to the manufacture of shoes and is hereinset forth illustratively, 'but not by way of limitation, with particuportions of shoes. 7

It is usual in the manufacture of shoes to provide a shank stiffener, fre uently of metal, which extends from the hee seat porlar-reference to the stiffening of the shank tion of the shoe through the shanktoward' theball line. It is usual in the manufacture 1 of turn shoesjto attach this metal stiffener to a leather orfiber member which is of a contour corresponding to that of the rear portion of the sole thereof and which itself is attached to the solo by appro riate means. While such a stiffener-is deci edly helpful in maintaining the shape of the shoe it does not have the same sti ening effect that it would have if applied directly to the sole itself.

It is an object of my invention, accordingly, to provide for the attaching. of such a stlfiener to the outsole of a shoe and to attach the stiffener, moreover, in a manner which will be ap licable, though by no" means limited, to t e manufacture of turn shoes. To do this the stiffener must be capable of attachment to the sole after the' shoe has been turned since it is evident that a sole with a metal shank stiffener attached thereto could not be turned. My invention provides forsuch attachment after the shoe has been turned. A further object of my invention is to provide for the utilization of such a stiffener.

' accordingly, vis to provide for the clenching It is a further object of my invention to do this in a manner which is applicable to turn shoes, in which case the shank stiffener must be attached to the sole after the sh has been turned.

With these and other objects in view rovision of a shank stiffener having a de ecting surface or surfaces which, whenthe stiffener is placed in contact with the sole of a shoe, will deflect a suitably driven fastener, such, for example as a staple, so. that its prong or'prongs will extend at an acute angle into the sole and be then somewhat bent 'so thatthe ends of the fastener embedded in the sole will be arranged approximately parallel to the surface thereof, and, if the sole .with reference to the accompanying draw-x ingzs and-pointed out in the claims.

igure 1 is a perspective view of'a shoe partly broken away so as more clearly' to show the invention;

Fig. 2 is a cross-section through the shank of the-sole of the shoe of Fi .1; and

ig. 3 is a section throng the same portion of a slightly modified shoe.

In the drawings, 10 represents the soleof a turnshoe, shown in Figs. 2 and 3 as of rubber and provided at or near its upper surface'with a layer of fabric 12, such as canvas, for the purpose of reinforcing the same. A depression leis provided at about the middle of the shank portion of the shoe for instance by molding, if the sole is 0 rubber. A I

The shank stiffener of the invention consists of a striplfi of! suitable "metalprovided at its median portionwith a pair of slots 18' and having the material of the body of the shank adjacent .to and between i the slots deformedas at 20, so as to provide a pair ofinclined portions the lower parts of which may-be positioned in the depression 14 of the sole and which will deflect theends of a fastener such as a staple 22 when" the latter is placed with its ends'in contact points will be deflected so as to enter the shank stiffener is molded or otherwisev sole at an acute angle to the upper surface thereof and will take up their final position approximately parallel to that surface as clearly shown in Figs. 2 and 3. a

An additional fastener such as a tack or nail 24: may be provided to attach the rear portion of the shank stiffener to the sole.

In the modification of. Fig. 3, a depression 26 extending the entire length of the formed inthe sole so that the upper surface of the shank stiffener will be flush with the upper surface of the sole, and this depression is provided with a deeper portion 28 to receive the deformed portion of the shank stiffener.

Although the invention has been described with reference to the illustrated turn shoe, it is to be understood that this is to be taken only as an exemplification thereof, and that the invention is not to be limited in its scope thereby, being clearly applicable to the manufacture of shoes of other types.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. The method of uniting a sole and a shank stiffener which comprises placing the I shank stiffener in contact with the surface of the sole and then drivin a fastener through the shank stiffener am? into the sole and at the same time deflecting it as it enters the solo at an acute angle to the upper surface of the sole thereof and embedding the portion thereof which penetrates the sole between the upper and lower surfaces of the sole.

2. The method of uniting a sole and shank stiffener which comprises placing the shank stiffener in contact with the surface of the sole'and then forcing the prongs of a multiple-pronged fastener into the sole in diverging directions, while straddling a portion of the shankstiffener, and embedding the end portions of the prongs in the sole.

3. The method of uniting a sole and a shank stiffener which comprises placing a shank stiffener in contact with the surface of the sole and then forcing the prongs of a multiple-pronged fastener through the shank stiffener and into the sole and at the same time deflecting said prongs so that they enter thesole and .assume a final position between the surfaces of the sole and approximately parallel thereto.

7 4. The method of uniting shoe parts which consists in placingsaid parts in contacting relation, and driving a multiplepronged fastener through one and into another of said parts and at the same time laterally deflecting the prongs of the fastener in opposite directions and embedding them in said last-named part approximately parallel to the surface thereof.

5. A shank stiffener provided with an aperture and an inclined surface adjacent thereto to deflect a fastening member as the latter is driven into a shoe sole.

6. A shank stiffener provided near its median portion with a pair of parallel slots and having a pair of inclined diverging fastener deflecting portions adjacent the said parallel slots.

7. A shank stiffener having a pair of apertures with a pair of oppositely inclined surfaces adjacent thereto to deflect the prongs of a staple as the latter is driven throu h the aperture into a shoe sole.

8. g shank stiffener provided near its median portion with a pair of slots and having a pair of inclined, diverging, fastener deflecting portions adjacent to said slots and a fastener receiving opening ad jacent to its rear end.

9. The combination of a sole, a shank stiffener contacting therewith and provided with a pair of inclined deflecting surfaces, and a fastener straddling said deflecting surfaces and extending into the sole in a direction approximately parallel to the surface thereof.

10. The combination of a sole, a shank stiffener contacting therewith, and a fastener straddling a portion of the shank stifiener and having its ends embedded in the sole and approximately parallel to the surface thereo 11. A shoe having a rubber sole with a sheet of reinforcing fabric embedded therein, a shank stiffener contacting with said sole and provided with a pair of inclined deflecting surfaces and a fastener contacting with the deflecting surfaces of the shank stiffener and penetrating the reinforcing fabric and the rubber of the sole, and having its ends embedded in the sole beneath the reinforcing fabric.

12. A shoe having a sole, a shank stiffener therefor rovided at its median portion with a pair of fastener deflecting surfaces, and a pronged fastener engaging the deflecting surfaces of the shank stiffener and having its prongs embedded in the sole and deformed and flattened by the action of the deflecting surfaces so that its ends are positioned in the sole approximately parallel to the surface thereof.

13. A shoe having a sole with a depression therein, a shank stiffener in contact with the sole and rovided with a pair of parallel slots and having the material between the slots deformed and depressed so as to occupy the depression in the sole, and a fastener contacting with the deformed 1,aoe,ses Y 8 portion of the shank stiffener and extend the shank stiffener and having its prongs 10 mg therefrom into the sole at an acute anembedded in the sole and deformed and gle to the surface thereof. flattened by the action of the deflecting sur- 14.
